In one compound of lead and sulfur, there are 6.46 g of lead
timurjin [86]

Answer:

Lead to Sulfur = 2 : 1

Explanation:

Given

Represent lead with L and Sulfur with S

L1 = 6.46g for S1 = 1 g

L2= 3.23g for S2 = 1 g

Required

Determine the simple whole number ratio of L to S

Divide L1 by L2

L = L1/L2

L = 6.46g/3.23g

L = 2

Divide S1 by S2

S = 1g/1g

S = 1

Represent L and S as a ratio:

L : S = 2 : 1

Hence, the required ratio of Lead to Sulfur is 2 to 1

What is it like on Mars? Please type 6 good answers.
valkas [14]
It's red because of rusty iron in the ground. Like Earth, Mars has seasons, polar ice caps, volcanoes, canyons, and weather. It has a very thin atmosphere made of carbon dioxide, nitrogen, and argon. There are signs of ancient floods on Mars, but now water mostly exists in icy dirt and thin clouds.

How many moles of oxygen are produce dif 11.0 mol of al are produced
ycow [4]

Answer:

8.25 moles

Explanation:

Given parameters:

Number of moles of Al produced = 11 moles

Unknown:

Number of moles of oxygen produced = ?

Solution:

To solve this problem, we need to understand the problem.

The decomposition of an aluminium oxide must has produced oxygen and aluminium,

              2Al₂O₃   →  4Al  + 3O₂

now since the known is the oxygen gas; we can find the unknown aluminium:

                3 mole of O₂ was produced with 4 mole of Al

               x mole of O₂ will be produced with 11 moles of Al

 x  = \frac{3 x 11}{4}  = 8.25 moles

A purple rock as a mass of 316 grams and a density of 5.9 g/mL. Determine the volume of this rock in mL.
MakcuM [25]

Answer:

The answer is

<h2>53.56 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}  \\

From the question

mass of rock = 316 g

density = 5.9 g/mL

The volume of the rock is

volume =  \frac{316}{5.9}  \\  = 53.5593220...

We have the final answer as

<h3>53.56 mL</h3>

Hope this helps you
